Abstract
OBJECTIVE: To analyze the epidemiological characters of fresh maxillofacial fractures in hospitalized patients by the retrospective study. METHODS: From Jan. 2008 to Dec. 2013, a total of 1 009 patients with fresh maxillofacial fractures treated at Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology were investigated. The data were statistically analyzed by SPSS 21.0. RESULTS: The male and female ratio was 2.94:1 and 33.5% of the patients aged from 20 to 30 years. The most common cause of the fresh fracture was road traffic accidents (424 cases, 42.0%), followed by tumblings (250 cases, 24.8%) and violence (128 cases, 12.7%). The number of new fracture was increasing gradually in recent years. The patients were at peak of 20-29 years old. The mandibular fracture was the most frequently seen (536 cases, 53.1%), followed by zygomatic complex fractures (233 cases, 23.1%). The simple maxillary fracture was rare and usually combined with other fractures. Infraorbital nerve injury was the most common one in nerve injuries (144 cases). The most common associated injury was extremity injuries (77 cases), followed by thoracic injury (65 cases) and craniocerebral injury (57 cases). Associated injuries were mostly caused by car accidents (127 sites), followed by fall (32 sites). Logictic regression analysis showed that fall and tumbling were risk factors of mandibular and condylar fracture (OR > 1, P < 0.05), while age was a protective factor (OR > 1, P < 0.05). CONCLUSIONS: Oral and maxillofacial fresh fractures most commonly occurred in young people, and the most common cause of fractures was road traffic accidents. Infraorbital nerve was involved frequently. The most common associated injuries was extremity injuries.
